I want the dump valve on my s2 Rs turbo to be as loud as possible . I currently have a forge fast-road item, which i believe is a group 'a' or summat (or did i just make that up-im not sure) but its not quite as loud as the bailey i had on my old rst. If anyone would like to swap my one for a baileys then let me know, also will it be louder if i take off the foam filter? Or will it ruin it? P.s Padvg or whatever i know your views so don't have a go at me!!

 

If you want more 'blowin' sound, buy one with a horn on it, or a blower... don't know how to call it.

Ask for it at your car modify shop...

 

ur sad man

 

just got a spec-r one and its real loud!

 

Get a bailey "Venturi" dump valve, the one with the trumpet outlet

 

baileys dv26 are nice

 

I've got the same forge dump valve as yours except it hasn't got the foam on, i think its just an extra, it should be fine, mine sounds mint.

 

i.ll try taking the foam off then, cheers.

 

How much boost are you running obviously the more boost your running the louder your dump valve will sound. I have a bailey DV26 twin piston dump valve and it sounds the buisness. I notice since i had my car chipped the dump valve sounds much louder. going from 7-9 p.s.i up to 17 p.s.i what a big difference it made

 

Dump valves are

 

Why do you think dump valves are . Are they just sales gimmicks because i thought a dump valve makes your turbo last longer because with out one you get back pressure on the bearing or as its called (compressor stall)and they also help with lag and also sound nice. I suppose everyone has their own opinion

 

They dont make it last any longer bottom line is they run better without dump valves on majority of cars is just to get noticed and serve no purpose , dont get me wrong some of the BIG booster cossies/rst`s may be better off with one

 

have tried my car loads now with dv on and off and cant notice any improovement in running so its defo getting left on!

 

sad!

 

I know what you mean mate.My pal has a Stage 1 Saff and i told him to loose it but i drove it before AND after and there was no difference

But on my Turbo there is a massive difference

Strange one...?

 

P.s Love the look of your Saff Wanted it when it was for sale

 

cant explain but is a difference there

 

Run so much better without.

 

Can someone tell me in what way does your motor run better with out the dump valve does it idle better and run more smooth.So if i was to take my dump valve off will i get the chatter sound let us know.Im running 17psi

 

it wont idle better! but will run smoother when ya change gear on boost it wont jerk! and you should get a little chatter! an it wont sound like a bus!

 

james what jerk?

 

Its boosting at 10psi

 

i bought a twin piston forge motorsport item when my car was running standard boost (7 psi) and it wasnt enough to actually force the piston back and dump one off.
I took it back to larkspeed and swapped it for another, this time it was there but only just. Sounds a lot better at 15+ psi

 

There is a company called turbosmart that make adjustable d/valves in max power etc. get one from them, it will cost ya tho...

 

Doesnt jerk , try it and ull see for urself , then if u dont like it put it back on im vouch for it ran with d/v for adges then took it off and feels great just so smoooottthh

 

i heard d/v are for only big boost cars but dont really make a difference on low boost turbo cars

 

Taken off the foam filter now and at same time cleaned valve with wd40 & hot water, now twice as loud and a sharper sound.

 

I had a DV on my old one for 3 months out of the 6 i had it, i took it off aweek before i sold it and wished so much that i hadnt put it on. Drives soooooo much better without oneon!!!!

Each one ot their own though!!
